Ok if any of you have changes plugs in a ford 5.4L 3V you know why i'm writing this..
I work at ford dealership in eastern,ontario,canada i have done about 30 of them now
The best way to get them out i found
Step 1: Do an engine flush (we use teraclean) removes carbon
Step 2: after flush run the piss out of it for about 30 mins
Step 3: park vechical overnight
Step 4:Push vechical in don't even start it
step 6 change plugs
this seems to remove and or soften the carbon build up on plugs so you don't break them off in the chamber.
Now of course this is not a guarantee this is what i've been doing seems to be the best method so far if you have any other please share.
 
IF YOU BROKE OFF THE PLUG OFF IN CHAMBER AND NEED FORD TSB FOR INSTRUCTIONS TO REMOVE IT EMAIL ME hemi_man_80@hotmail.com and ill mail you the TSB in .PDF format(adobe reader) ]
---------------------------------------------------
ADDED NOTES:
After reciving many emails there is some other tips I would like to add too.
When your turning the plug if it creeks thats a good sound means the shaft is moving its when it stops creeking you have to stop try re-tightening a bit loosen a bit then fill plug cavity with carb clean and let it sit for a bit. sometimes this helps.

We run the vehicle to operating temp and then remove coils, loosen plugs and spray penetrant. Have a cup of coffee or leave it overnight(dependant on time of day. Then it usually comes out fairly easily. Was nice to see the tools available aftermarket now. We borrowed one from Ford and had a machinist friend of mine make us a set. We only have had 1 spark plug break out of 6 vehicles. Might try your way to see how the techs like it.

there is also a TSB for putting Motocraft high temp anti-seize on the shaft of the plug to prevent carbon build up.. not sure how well that works overtime yet.

I don't think it has to be Motorcraft. I bought a bottle or Motorcrsft and found it is nickel based anti-sieze. Might look for a cheaper brand to see if it works.
I just now noticed you had 2 Champion plugs shown. I have never had good luck using Champion in any product but Chrysler. We compared 4 Champion and 4 Motorcraft in same vehicle (4.6L Crown Vic) and after 15k the Champions were misfiring. The Mororcraft were left in for over 80k before we had to change them. Just my opinion of course.

Way2; When my hemi was still fairly new, all that was available was Champion. Normally, I wouldn't put Champions in my lawnmower, but had no choice. Now, they are available in Autolite, and am sure other brands, as well.
Gettin' old, but seems that there were some big block Fords (351M/400 maybe) that would carbon up the threads just below the head surface and would damage the threads on the way out. We used to use (this is back in the early 70's) combustion chamber cleaner prior to removing them. Seemed to work great. At the time, we got it from The Schraeder Co. in So. CA. They also made it for GM and Kiekoffer(inc.)/Mercury. Now, we use the MotorVac.

Speaking of plugs - I've had at least six Champions in taper seated applications that were both rusted and probably overtightened leave just threads in the hole and not hex! Found a pic which just happens to show an NGK but the Champions did it the most. Scares the crap out of you then trusting a screw extractor to remove just the threads.
Been using just silicone smear on the taper which was the problem with typical old GM plugs and no problems since on any brand.
I'm with Loren on where that brand belongs - on the store shelf unless there's any alternative! Get's hard finding non Champions for weed whackers and so forth though
Pic of what was happening too much to me but the NGK shown,

** Update ** Well as i discovered today dosen't work well with vechicals with over 200km lol.. I did one today broke 7 out of 8 off.. don't want to go back to work on monday going to be there a while.. I herd that a company has made a 1 pice plug so they don't break off.. wondering if any of you have tryed them?..we had a customer with NGK plugs and ran like a bag of Sh!t.. I think Champion makes them not sure.. since i have 05 F150 5.4 I change mine once evey 60 km (30.000 miles roughly) its a bit of a pain in the ass at $15 a plug.

Maybe want to see if you can get stainless steel plugs. We put some in the 460's when the originals rusted in the heads. Not sure where they came from though. I thimk AC Delco makes them.

ive had better luck by just spraying them
down with a little liquid wrench or wd40 and letting
them sit for 2-3 hours on a cold engine that seems
to work for me but maybe not practicall for a
tecknition to do especially when your paying
70=80 $ bucks an houre for him to do that a way
